Ingersoll Rand 2145QiMax 3/4-Inch Composite Review

Ingersoll Rand is a well-trusted brand in the automotive and heavy machinery industry. They have a history of producing high-quality products at a fair price, and their tools are always built with long-term efficacy in mind.

The 2145QIMAX, or HD Max ImpacTool, from Ingersoll Rand is a heavy-duty, professional grade air impact wrench. It is compact but extremely powerful, and makes what used to be a tool only for heavy metalwork shops convenient for use in any workplace. This review will walk you through all the features of the 2145QIMAX in detail – from the things we love, to the things it could improve on.

1. The Basic of 2145QiMax

Ingersoll Rand 2145QiMax is a popular tool across industries. It is designed to be compact and efficient without sacrificing on power – ideal for heavy truck and bus maintenance, professional or semi-professional construction or agricultural repair.

2145QiMax can produce up to 1,150 blows per minute, with an average free speed of 6,300 rotations per minute. It uses a unique twin hammer mechanism for consistent torque, and comes with Ingersoll Rand’s patented power regulator dial with four power settings, for a range of versatile uses. A newly-designed 7-vane motor uses 16% less air to operate than comparable tools.

One of the best features of the 2145QIMAX, and what makes it so popular among professionals, is that it is incredibly quiet for the power. It produces 91.1dBA of sound pressure while in free speed mode.

2. The Design of 2145QiMax

The design of 2145QIMAX is all about efficiency, convenience and usability. At just 7.4 pounds, it is lightweight enough to be used with one hand – making it perfect for tough-to-reach jobs. It is also equipped with Ingersoll Rand’s patented one-hand forward/reverse system, so you can easily switch between settings without using your free hand.

The newly-designed Ingersoll Rand motor is meant to increase power while significantly decreasing air intake, which in turn means this impact wrench uses less energy and saves you money in the long run. The reduced noise makes 2145QIMAX more comfortable to use in any shop or work setting, especially indoors. 

Not only is it light and powerful, it is also highly durable. A tough steel wear plate protects the end plate, and Ingersoll Rand 2145QiMax features an inlet prescreen that can be easily cleaned, and prevents dust and debris from entering and damaging the machine.

3. Accessories and Warranty Information

The 2145QIMAX comes as an individual product, without an additional battery or charger. A protective cover can be purchased separately to add to the tool’s longevity.

It does come with a 2-year total warranty from Ingersoll Rand.

Things we liked

All things considered, I was highly impressed by the performance of the 2145QIMAX. It is light, easy to operate with one hand, and surprisingly quiet compared to other shop power tools. It can get the job done quickly without much of a headache.

One of the best features of this little impact wrench is its durability. This thing is made to stand up to daily uses in any conditions – it can be tossed around, stored anywhere, constantly used, and it will show no signs of wear. It definitely lives up to Ingersoll Rand’s industrial quality reputation.

Things we didn’t like

In all honesty, there is not much to complain about with this air impact wrench.

Ingersoll Rand 2145QiMax is a little more expensive than other products of the same type, and any accessories you want have to be bought separately. However, with its efficiency, you will save money on energy and compressed air in the long run. Overall, the quality is definitely worth the cost.

 As a final note, while this tool is quieter than I expected, keep in mind that it is still a power tool. There will be some noisiness – just not quite as much as with other impact wrenches.

4. Conclusion

The Ingersoll Rand 2145QIMAX is a highly efficient, super powerful industrial grade tool. I recommend it for semi-professional to professional use on heavy automotive service and construction tasks.

 If you are looking for an impact wrench that is quieter, lighter and less wasteful, while still powerful enough for any task, this HD Max ImpacTool is certainly the right choice for you.
